I sing and play guitar just enough to get the song across so a demo studio could give me a pro demo. One studio used my vocals and just worked the music around my voice; this was long before AI. Didn't sound too bad but I knew it was me and my voice leaves a lot to be desired LOL I have not used AI yet, not likely to. I'm mainly into Christian songs which I send to CCLI with just me singing with the guitar. If churches like my songs, they will use them with the music choir performing them, all they need is the lyrics and rough tune so they know how it should be sung. I'm pleased at how many songs get used, I get a royalty each time the songs get picked up in the sampling, much the same as radio, If it gets picked up in one sample, it might be used in 100 other churches that are not being sampled that week, you get nothing from them, like I said, just like radio. Not getting rich by any means, averaging about a thousand dollars a month.
